The apparatus used is Cylindrical measure and plunger, Compression testing machine, IS Sieves of sizes – 12.5mm, 10mm and 2.36mm Procedure to determine Aggregate Crushing Value i) The aggregates passing through 12.5mm [ ].
The aggregates crushing value test should be performed as per IS code 2386 Part IV. First, fill the sample aggregate with one-third of the cylindrical measure in three layers. Each layer should be tamped 25times freely. After filling the sample aggregate, weigh and record it as W1. Now fill the aggregate in the mould along with the plunger on top.

Feb 05, 2012 3.2. Aggregate Crushing Value (ACV) Determination . The Aggregate Crushing Value is a value which indicates gradually applied compressive load (a California Bearing Ratio (CBR) machine or concrete crushing apparatus) over a period of 10 minutes, after passing through sieve 14.0mm, and retained on 10.0mm sieve. The retained materials were.
The value obtained suggests a higher aggregate strength even though there is no explicit relation between the crushing value and compressive strength for any given aggregate, Neville (1981). The impact value of 15.45 indicates the adequacy of the aggregate to be used in concreting (BS 812 part 3.
This may be assessed by tests of aggregate impact value (AIV) and aggregate crushing value (ACV). The common rock types range in AIV from good (basic volcanic, dolerite, quartzite. quartz gravels), through fair (granite, gravels composed of igneous or metamorphic fragments) to poor (weathered igneous rocks, clay-rich gravels).
